Hepatocellular carcinoma (HCC) is the third most common cause of death related to cancer diseases worldwide. The current treatment options have many limitations and reduced success rates. In this regard, advances in gene therapy have shown promising results in novel therapeutic strategies. However, the success of gene therapy depends on the efficient and(More)
New micro three-dimensional (3D) scaffolds using biobased unsaturated polyesters (UPs) were prepared by microstereo-thermal-lithography (μSTLG). This advanced processing technique offers indubitable advantages over traditional printing methods. The accuracy and roughness of the 3D structures were evaluated by scanning electron microscopy and infinite focus(More)
Cationic polymer-based vectors have been considered a promising strategy in gene therapy area due to their inherent ability to condense genetic material and successfully transfect cells. However, they usually exhibit high cytotoxicity. In this work, it is proposed the use of a tailor-made gene carrier based on a tri-block copolymer of(More)
Gene therapy is considered a promising approach for the treatment of hepatocellular carcinoma (HCC). In this regard, the main goal of this work was to develop a specific and efficient gene delivery nanosystem to HCC based on 1-palmitoyl-2-oleoyl-sn-glycero-3-ethylphosphocholine:cholesterol cationic liposomes and asialofetuin (ASF), a specific ligand to the(More)
This manuscript reports the synthesis of a new cationic block copolymer based on poly[2-(dimethylamino)ethyl methacrylate] and poly(β-amino ester) from different polymerization strategies. For the first time, it is proposed a triblock copolymer based only on cationic segments, aiming a high biocompatibility, enhanced buffering capacity and(More)
